Hi guys does it appear my corrector plate requires a clean?

 

Last night used one of those bulb shaped rubber blowers on close look there appears some black smudges on the upper right of corrector plate, there is also that white speck whatever it is. The smudges look a bit like finger marks but nobody else has been handling the scope. Or maybe that area is the normal bit and it's surrounded by layer of dust!? - see how little i know!

 

Not really sure have used the scope only few times over past 2 weeks where before it was in attic for over a decade

I have cleaned mine once in 15 years. There is a joke about never looking at the plate as it will almost always give you the urge to clean it. What you see will not change your view at all. If you do decide to clean it, be very careful so you don't damage the coating. Personally, I would just quit looking at it other than through the other end of the scope!!

It actually looks like a bit of contamination has built up on the corrector over the years, and probably on the inside. That is not unusual. You can restore it to excellent condition if you are handy. It is not too difficult to remove the front plastic ring, mark an index line on the edge of the corrector and tube so you get it back in right, take out the corrector and wash it gently with water, a drop or two of soap, and cotton balls. However there are a number of steps to this you have to be careful with or you can make a mess of your scope. You can check the internet since there are a number of sites that describe the process.

 

The haze will affect the view, but by not very much. If you are not one who regularly takes stuff apart (and successfully gets it back together) its probably better to leave it alone as nitegeezer says.
